Nausea, diarrhea, palpitations, chills, restlessness, confusion, lethargy –> myoclonus, hyperthermia, rigor and hypertonicity
Discontinuation syndrome
Most commonly with paroxetine, fluvoxamine, venlafaxine
Common mood stabilizers
1st line: Lithium Lamotrigine Divalproex 2nd line: Carbamazepine
Lithium monitoring
Before starting: UA, BUN/Cr, thyroid function, ECG if heart disease
Serum levels every 5-7d until therapeutic (wait 12h post dose)
Then monitor monthly
Then q2-3mo
Monitor thyroid function, Cr q6mo and UA q1y
Acute mania tx
Lithium
DIvalproex
Carbamazepine
NOT lamotrigine
Lamotrigine monitoring
No therapeutic plasma level established, titrate based on response
Slow titration due to risk of SJS
A/E: SJS, fever, swollen glands, severe muscle pain, bruising, headache, neck stiffness, vomiting, confusion, increased sensitivity to light
Divalproex monitoring
Monitor serum levels q5-7d until therapeutic
LFTs weekly x 1mo then monthly then q2-3mo due to risk of liver dysfunction
Divalproex drug interaction
OCP
Carbamazepine monitoring
Monitor serum levels q5-7d until therapeutic
Weekly blood counts for first month due to risk of agranulocytosis
Carbamazepine drug interaction
OCP
Lithium toxicity
Clinical dx as toxicity can occur at therapeutic levels
Caused by OD, fluid loss, concurrent illness, NSAIDs or diuretics
N/V/D, ataxia, slurred speech, poor coordination, polyuria, drowsiness, myoclonus, tremor, UMN signs, sz, delirium, coma
Tx: D/c for several days and restart at low dose when level falls to non-toxic range, saline infusion, hemodialysis if high levels, coma, shock, severe dehydration, failure to respond to tx after 24h or deterioration
Benzo MOA
Strengthen binding of GABA to receptors –> decreased neuronal activity
Benzo antagonist for OD
Flumazenil
Buspirone MOA
Partial agonist of 5-HT1A receptors
Benzodiazepines safe in pts with impaired liver function
LOT
Lorazepam
Oxazepam
Temazepam (should be avoided)
ECT
Induction of generalized sz using electrical impulse through scalp electrodes while pt is under general anesthesia with muscle relaxant
Repetitive transcranial magnetic stimulation (rTMS)
Focal electrical currents in select brain circuits using magnetic induction
Form 1
Right to hospitalize pt for psych assessment against his/her will
Valid for 72h
Form 2
Right to bring pt in for psych assessment against his/her will
Valid for 7d
Form 3
Certificate of involuntary admission to facility
Completed by any MD other than MD who completed Form 1
Valid for 14d
Form 4
Certificate of renewed involuntary admission
First: 1mo
Second: 2mo
Third: 3mo (Max)
Form 5
Change to informal/voluntary staus
Risperidone
Atypical antipsychotic of choice if wanting to avoid sedation
Narcolepsy
Excessive daytime sleepiness
Cataplexy (emotion causes physical collapse)
Hypnagogic hallucinations
Sleep paralysis
Narcolepsy tx
Methylphenidate and other stimulant drugs
Tourette syndrome
Common genetic neuro disorder manifested by motor and phonic tics with childhood onset
Symptoms must occur for more than 1yr
Tics = involuntary, sudden, brief, intermittent movements or utterances that present with irresistible urge before and relief after
Treatment for tics
Alpha2-adrenergic drugs (Clonidine, Guanfacine)
Antipsychotics (risperidone best studied)
Botox
Psychotherapy
Antipsychotics and galactorrhea
DA RESTRICTS prolactin release
Antipsychotics decrease DA –> increased prolactin –> galactorrhea (+menstrual irregularities, infertility)
Most commonly seen with first gen antipsychotics (haldol, fluphenazine) and 2nd gen (risperidone and paliperidone)
Somatic symptom disorder
At least 4 pain symptoms, GI distress, Sexual problems and pseudoneurological symptoms
Begins before age 30
Bipolar tx duration
Indefinite tx with mood stabilizer
Kindling phenomenon = episodes occur more frequently, more severe and less responsive to tx if tx is stopped
Early morning awakening - depression or anxiety?
Depression
Difficulty falling asleep - depression or anxiety?
Anxiety
Apprehensive expectations or feelings of dread - depression or anxiety?
Anxiety
Voyeuristic disorder
Sexually aroused by watching someone who is disrobing, naked or engaged in sexual activity

AOO 7yo
Vocal and/or motor tics which occur several tism a day for a minimum of 4 wks, however, no logner than 12mo
Dx CANNOT be made if pt has EVER had a hx of Tourette’s
Acute stress disorder
> /= 3d and =1mo following trauma
If >1mo, then becomes PTSD
Most common S/E a/w Olanzapine
Weight gain
Psych drug a/w diabetes insipidus
Lithium
Amenorrhea from prolactin elevation most commonly seen with
Palliperidone
Risperidone
Atypical antipsychotic monitoring
Metabolic adverse effects: BMI Fasting plasma glucose Lipids BP Waist circumference Baseline, at 3mo then annually Olanzapine and clozapine pose greatest risk
Lithium C/I
CKD –> use Valproate instead
Heart disease
Hyponatremia or diuretic use
Common drugs affecting lithium levels
Diuretics NSAIDs, EXCEPT ASA SSRI ACEi/ARB Antiepileptics
Wellbutrin C/I in what medical condition
Epilepsy
Lowers sz threshhold
Psych med known to cause hypothyroidism
Lithium
Baseline thyroid function tests should be mesaured prior to starting Li therapy and monitored 3mo after starting and 6-12mo thereafter
Recurrence of depression
6x risk boys, 4x risk in girls
Recurrence more common with family hx
Mean # episodes over lifetime is 5-6
Mean # episodes of bipolar over lifetime
8-9
